Since
ver. 15.02.15 of BMW Explorer user can choose between 3 variants to program
ignition key
1. Variant
NOTE: Please
ensure that key slot is unblocked before to program the new key there.
If you have all
keys lost, you must answer NO when BMW-Explorer ask if you have working key.
BMW-Explorer will then extract crypto from DDE/DME and EGS GS19D (if
available). Your PC must be connected to Internet to fulfill this
procedure.
Also it will
read ISN from the CAS module and automatically fill the CRYPTO fields in the
working window of BMW Explorer.
If all the
fields are match each other it means that crypto is correct and you can use any
field. For example we can choose EGS crypto, then upload *.bek file, press
write (red button) and just follow on-screen instructions. Then start a car.
If your car has
DME/DDE with ews3 system and you are going to use EGS crypto, you must answer
YES after BMW-Explorer asks you about “CFG”. Then simply wait the finish of the
programming procedure. Don’t forget to make DME-CAS sync in DME menu (this step
is not available for DME/CAS with ews4 )
In case if you
see a different values in the DME crypto and EGS crypto fields, you can try to
program the key using each field in turn.
After the key
successfully programmed you must check a key status field
002B00- for
pcf7936 chip
004B00- for
smart key
005B00- for
keyless-go key
Note: When you
are using this way of key programming, make sure than DME/DDE-CAS-EGS belongs
to the SAME car
2 Variant
Please ensure
that key slot is unblocked before to program the new key there.
This variant is
usable for a cars equipped with Bosch and Siemens DME/DDE with ews4 16 bytes
long ISN code AND you have a possibility to read out ISN from DME/DDE.
BMW-Explorer can
read ISN (SecretKey) from the following DME/DDE types-ME17N45 , MEV17_2 ,
MED17_2 , MV1722 , MVD1722 , MEV17N46 , MEVD176k , D7xN47xx , D7xN57xx , MSS60
If you got above
listed DME/DDE, but BMW-Explorer was unable program key automatically, you must
go to DME/DDE (Extra functions), read ISN manually and copy it. After that you
must return to the CAS, select Key learning, answer NO when BMW-Explorer ask if
you have working key, tick DME ISN box and Paste copied ISN into this field,
then upload *.bek file, press write (red button) and just follow on-screen
instructions. Then start a car.
After the key
successfully programmed you must check a key status field
002B00- for
pcf7936 chip
004B00- for
smart key
005B00- for
keyless-go key
3 Variant
Please ensure that key slot is unblocked before to
program the new key there.
You can TRY to
program key by the following way:
1. Read CAS
eeprom using any of suitable programmer (X-prog,ETL etc.)
Note: For the
CAS modules programmed with ISTA36-42 (bmw numbers 9221719 , 9226238 , 9221720
, 9227053 , 9226238 , 9217853 , 9226239 , 9217854 , 9227053 , 9226239 , 9227106
, 9217854 , 9230590 , 9227053, 9230591 , 9226238 , 9237046 , 9221720 , 9237047
, 9221719 , 9237046 , 9237047), open read eeprom in the HEX Editor and write
down values from the 02 and 03 columns in the 1 and 2 rows (as pictured)
2. Note: For the CAS modules programmed
with ISTA43-55 (bmw numbers 9253119 , 9253120 , 9257219 , 9253119 , 9257220 ,
9253120 , 9262360 , 9262361 , 9267608 , 9267609 , 9273192 , 9262360 , 9273193 ,
9262361 , 9278745 , 9267609 ,
9278746 ,
9267608 , 9283153 , 9278746 , 9283154 , 9278745 , 9287534 , 9283153 , 9287535 ,
9283154 , 9314256 , 9287534 , 9321069 , 9314256) ), open read eeprom in the HEX
Editor and write down values from the 00 and 01 columns in the 1 and 2 rows (as
pictured)
Install CAS3+ back to the car, go
to CAS, Extra functions, Key learning, answer NO when BMW-Explorer ask if you
have working key,
wait for key data, tick Selection
CFG box, enter upper 2 bytes from HEX Editor into first field, enter the lower
2 bytes from HEX Editor into second field.
Then upload *.bek file, press
write (red button), after some time BMW-Explorer will ask you to insert a key
into the key slot. Enter a key and press OK. After some time BMW-Explorer will
ask you about “CFG”, press YES and wait the procedure finish. Key programming
can take up to 2,5 hours, therefore BATTERY CHARGER MUST BE CONNECTED TO THE
CAR!!!
Note: When
you are using this way of key programming, make sure than DME/DDE-CAS-EGS
belongs to the SAME car
After the key
successfully programmed you must check a key status field
002B00- for
pcf7936 chip
004B00- for smart
key
005B00- for
keyless-go key
